Intel SpeedStep not working on Intel DP67BG Extreme Board!!! please help

[sankukai]

Guys.....

As some of you may now I recently upgraded to a brand new system and have been using gaming with an overclocked Core i5-2550K processor to 3.8 GHz and using Corsair Vengeance RAM at 1600 MHZ. Since I am using an Intel DP67BG Extreme motherboard, I used the Intel Extreme Tuning Utility to OC my processor. I simply increased the CPU multiplier to 3. 8 GHz on each core and nothing else. Yesterday something weird happened however. Both CPUID-CPUZ and CoreTemp indicated that even while idle, my processor would not downclock to 1.6 GHZ( which it did until yesterday) even though I have had Intel´s SpeedStep feature enabled from the Extreme Tuning utility's Manual Tuning panel since I first OC my CPu. So basically my processor operates at 3.8GHz even when not doing anything and core voltage levels now oscillate between 1.2800 to 1.3200 even if am just surfing the web.

I am very worried that I might have damaged some internal regulation system in my motherboard or perhaps something worse. I would really appreciate some advise on what could be causing this situation and whether it is safe for me to continue using my processor in its overclocked state.

Many thanks for your help

I don't know for your particular board, but there is several options you can tweak that will alter the speedstep...so reset your board's settings and start again...write all settings down...there is a right combination of settings that will OC with the downclock working proper....

On my Asus board/2500K, I disable all that, and I get a steady 4.5Ghz clock even at idle...I prefer it like that myself....

Remember, lowest temperature and lowest voltage for a stable OC is what's matter...

I find the downclocking features are nice for laptops (to save every bit of electricity), but for an overclocked rig, I find it's ALMOST pointless.....

Thanks for you comment dude.

I appreciate your advise but must say that I do want to have SpeedStep on just because it allows me to use less power and, I'll admit it, likes to save power whenever I can( even when overclocking) But i will see waht resetting my BIOS does will let all you guys know

Reseting all your setting is a good idea(so long as you write down what you had before you change them). You can also see if there is an upgrade to the Bios that might fix any potential problems that Intel may have coded into the original Bios.

This is the lastest, but BEWARE AND READ THE DISCLAIMER!!!

This is suppose to be unreversable if you upgrade...why I have no idea. but it did come out 7/17/2012.

Just make sure you don't use the high performance power profile (use the balanced one, and tweak it) on windows 7, as it disables speedstep.
